FOOT AND LAST MEASURING DEVICE.y

To all yTof/om t may concern: f

Be it known that l, lvlanorn F. CLARKE., a citizen of the United States,residing at lvllorcester, in the county of lVorcester and State`ofhlassachusetts7 have invented a new and useful Foot and Lastmeasuring Device, ofwhich the following is a s pecicat-ion.

My device is an instrument for quickly and accurately determining thelength and width of the human foot, or the Vlast upon which shoes aremade, in terms of shoe sizes as standardized in common practice. It hasbeen the special 'object of my invention to make a device which shallcombine accuracy with simplicity, strength, ease, and quickness ofoperation.

My device may be best understood by reference to the accompanyingdrawings in which:

Fig. l is a top view showing the device in operative relation with afoot shown in dotted lines.

Fig. 2 is a side elevation.

Fig. 3 is a bottom view with vthe casing partly broken away.

Fig. 4 is a section on line 4 4 of Fig. -1.

Fig. 5 is a section on line 5-5 of Fig. 4, viewed in the direction ofthe airow.

Fig. 6 is a section on line 6-6 of Fig. 4, viewed in the direction oftherarrow.

Fig. 7 is a section on line 7-7 of Fig. 4, viewed in the direction ofthe arrow.

Referring more specifically tothe drawings, 1 is a casing preferablymade of wood and provided with a Slot 2 which-.registers with acorrespondingslot in Ametallic plate 3 which is mountedflush with thetop of casing 1, and isprovided with a scale Aof shoe Sizes, in terms oflength, as shown in Fig. 1. A heel plate 4 is provided with a lug 5entering the wooden casing 1 which lug is tapered and threaded toreceive bolt 6 which passes th-roughwasher 7 and thus retains the heelplate 4 securely in place. A post 8 attached to the front of 'casingland extendingabove the top t-hereofisprovided with a hole 9 throughwhichpasses rod 10 which has at one end a knob 11 and at'the other end a. toeplatel which has a base 13 `slidablybearing on -theplate 3. The base,,'13 is shaped to 4form an indicator v14 with respect to the scaleonplate 3. Y.

Extending through slot v2 is 'a post 15 screwed into Vthe base 13 of toeplate This post 15 serves as a guide for sliding the Specication ofLetters Patent. .Patgnted Mar. 21, 1922 Application filed November 14,1919.

serial No. asspaej rod 10. The post '15 passes loosely through the'headof thumb nut 16 which is screwed into the forward endof the wedge 17 (tobe hereinafter described), which is freeto slide on the top of brassbushings 18 and 19 mountedbetween the sides of the casing 1 inholes'therein. On a downwardly bracket 205 on the rear portion ofthewedge member 17 is fastened a coil spring 21 which passes u-nder'thebushings'l and 19 and is attached tol the inside of the .forward end ofcasing 1 by screwhook This coil spring 21 tends normally to pull forwardthe wedge member 17 and the attached rod 10.

Side plates 23 and4 ofshape best shown in Figs. 6 and 7 are mounted toslidelaterally in the following manner: they are provided with lugs 25and 26 respectively in which are mounted rods 27 and 28 respectivelywhicht closely and slidably in the bushings 18 and 419. The ,side plates'23 and 24 are also provided with lugs 29 and 30 respectively in whichare mountedrods 31 and 32 respectively Awhich pass through bushingsand84 respectively in the sides of casing V1 and which are provided withinset hardened metallic tipsB and 36 respectively which are adapted tobear normally on opposite sides of wedge member '17, beingheld normallyin Contact therewith by means of coil spring37 which passes throughopposite holes .38 and 39 in casing 1 andis attached ateaclrend to aside plate. Abase plate 40 cofvjers the base of the casing and theparts'c ontained'therein. This plate 4D is'lieldin place-by screws 411,the heads of which are f sunk in rubber tips 42.

In assembling my device and adjustingit .for propermeasurement ofthefootor last,

I placein thedevice a last ofanylength size but of an Afwidt-h. Thiswill cause a certain separation of side plates 23and24. The device isthen turned over and, the plate V40fbeing removed, the position ofthewedgemember-17 is adjusted so that itbearsirmlyfon the points 35 and.36`by turning the -thumb Ynut 1 6 into such aposit'ionfthat whenthe'toeplate v12 butts againstthef'last, thep'ost l5 will passthrough theholeyin thefthumb nut. Thus when-a. foot or'last isof A' width thev :foot orlast will not separate thesideplates further thannecessary to allow `thefoot to be accommodated vbetween theheel and toe plates. If the footerlast `is wider than A width t-herod 10 will be pushed 'forward theextending Vdistance of a fullgradation on thescale for each unit ofincreased width. The reason @for this is found in the angular relationof the sides of the' wedge member 17 which per-V mits the wedge to moveforward, while remaining in contact with points and 36,`

' by the increased widthl ot a :toot or last; a

a like purpose.` The result of this, when itis distance Lof one-twelfthof aninch representing a widthsize in caseot mens shoes. The widthsizeof a womans shoe is one-sixteenth of an inch and thefuedge member isconsti-noted accordingly if the device is intended for measuring womensiieet. From the foregoing will be readily apparent the correctness of myrevious statementthat when an A width cip footer last, of` any lengthsize, is inserted in the device theV toe plate 12-on rod 10 will not bepushed further forward thanthe. toe of the tooty or last when it is alsounderstood that for every unit of increase oflength size the A width isone unit of widthvsize greater, that fis to say, in the case of mensshoes the A width of a seven. size is one-twelfth of an inch Vgreaterthan the A width ofa slice of: six size. l

The operation of my device is as follows: The foot or last to ben'ieasured is'placed betweenthe side pieces 23 and 2-iwvith heel buttedfirmly` againstthe heel plate 4t.- It

it is a left foot, as shown in Fig. 1, both side plates will slide inunison slightly to the left to permit the proper alignment of the footwith respect to theheellate ll and toe plate It it `is `a right Y ootVthey will slide aleft foot, is tothrowthe wedge `member 1T `to the left,as shown inf Fig. 3, this being permittedb its swivel attachment totheend of v rod 1,0..` he foot separates the side pieces 23 "and 24 againstthe action oit the spring 37 which holds the' side nieces in hrmengagement with the foot. The result of this separation permits theforward movement of the wedge member 17 which is actuated 'forward byspring 21. This in turn carries forward the rod 10 which isattachedthereto. `This will carry the toe piece 12.well forward of the toe ofthe foot accordingly as the foot ismore than an Width; The rod 10 maythen be pushed back to bring the toe piece 12 a einst the toeofthe oot.'The scaleonV p ate 3 is so Vpositioned that the reading on the`indicator oint 1 4 v`will then show the length-size of t e `footorlast. Thus in Fig.

1`th`e`reading` would be size 7; "The rod 10l may then be released'landwill slide forward automatically .a short distance. unit ofdistancetrayelled represents a width in excess of size A." n'lhusinF`ig.1the in- .6b

Each full dicatorwonld move forward from 7 to 10 'fitting slioesto thefoot.

Having thus fully described my invention, what I claim is: Y
